Product Overview
The 558003 Double-Ended Scleral Marker is a hyper-precision ophthalmic registration instrument characterized by its dual-sided architecture featuring fixed 3.5mm and 4.0mm caliper distances. Designed in strict accordance with elite vitreoretinal and pars plana vitrectomy (PPV) safety protocols, this instrument acts as a critical safeguards template to ensure surgical entry sites completely avoid both the peripheral retina and the ciliary body. Forged from high-tensile surgical steel, each end features a micro-machined, blunt marking tip calibrated precisely to surgical dimensions. By bridging the limbal margin, the tool provides a reliable, repeatable template for placing sclerotomies or intravitreal therapeutic injections with ultimate anatomical safety.
Key Features
-
Dual-Calibrated Aphakic Dimensions: Features a double-ended configuration with a 3.5mm safety profile on one end and a 4.0mm safety profile on the opposing end. These industry-standard benchmarks provide instantaneous, error-free measurement options tailored to phakic, pseudophakic, or aphakic eye profiles.
-
Atraumatic Blunt Marking Tips: The caliper tips are meticulously hand-beveled and rounded into a blunt profile. This design safely stamps a high-visibility indentation or ink mark onto the sclera/conjunctiva without causing deep tissue micro-lacerations or subconjunctival hemorrhages.
-
Ergonomic Octagonal Grip Handle: Designed with a premium, knurled centration handle featuring a solid tactile grip zone. This balanced architecture prevents lateral twisting or rotational slipping inside the surgical glove, suppressing micro-tremors during delicate alignments.
-
Glance-Free Satin Finish: Hand-beveled with an anti-reflective satin coating that dampens the intense illumination of the surgical microscope, minimizing visual glare and maximizing procedural clarity.
-
Surgical-Grade Resilience: Manufactured from premium, hardened stainless steel. It is built to maintain its hyper-precise 3.5/4.0mm fixed caliper tolerances and structural linearity through thousands of high-heat sterilization cycles.
